Sunderland have completed the deadline day loan signing of Manchester City full-back Wayne Bridge.
The former England defender has played just once for City this season after spending last term on loan at West Ham United.
He becomes Martin O'Neill's first signing since his appointment at the start of December.
"I’m hoping that with Wayne’s undoubted experience and ability he can be a big help to the team until the end of the season," O'Neill said.
"I’m very pleased to have him here and with the number of injuries we’ve sustained recently I’m sure he’ll be a great help to us."
The 31-year-old began his career at Southampton, before moving to Chelsea and subsequently Manchester City.
Bridge retired from international football in 2009 following headlines surrounding John Terry's alleged affair with his former partner.
He spent the second-half of last term on loan Upton Park, but could't prevent the Hammers from suffering relegation from the Premier League.
After Steve Bruce become the first Premier League casualty of the season, following two wins in the club's first 13 games, O'Neill has helped guide the club into the top half, having lost just twice since taking over in December.
